The channel capacity of the DT80 range of loggers can be increased by using the Channel Expansion Module (CEM20). Each CEM20 connects 20 universal data logging channels to the DT80 range of data loggers.
A CEM20 connects to one analogue channel of the data logger. This can expand the total channel capacity of the DT80 to 300 analogue inputs (common reference) and the DT85 to an incredible 900 analogue inputs (common reference). Incorporating the same dual isolation technology as the DT80 range data loggers each channel of the CEM20 can be used for two isolated inputs or three common reference inputs
